6. Time-Series from Date Strings

Write a Pandas program to create a time-series from a given list of dates as strings.

Sample Solution:

Python Code :

import pandas as pd
import numpy as np
import datetime
from datetime import datetime, date 
dates = ['2014-08-01','2014-08-02','2014-08-03','2014-08-04']
time_series = pd.Series(np.random.randn(4), dates)
print(time_series)

Sample Output:

2014-08-01    2.025858
2014-08-02    0.307073
2014-08-03   -0.903682
2014-08-04    0.056662
dtype: float64
